Why would myusername say caff was mafia if he knew she was not?
He's probably paranoid, because to claim cop the first day on a guilty investigation is weird, but at least now he knows he is probably paranoid. And why would the mafia try to take out a vanilla townie with a cop claim. It's illogical.
What about Dess?
If Dess were mafia trying to get myusername, then why wouldn't he have a report? It's like, "HEY GUYS, MYUSER NAME IS LYING, I'M THE COP... but I... I don't have any proof." What I'm saying is that if Dess was mafia, he would have a report on caff, saying she's town.
In conclusion:
My opinion is, they're both town.
Now, I don't know how the discussion has been going so far, as I type this while it is still night, so hopefully, nothing much has been said in the first hour.
Good point out by notty about ender's death, because I think a lot of the actions are after a certain amount of time during the day.
For example, I'm sending this message 1 hour after the day starts.
